This is probably one of the best reasons we should switch the main client to a more restrictive license, that wouldn't allow to redistribute a closed source client based on the original client.

Anyway am I the only one who's wondering if the reported performance is actually what is going on under the hood? It doesn't take a lot of effort to just multiply the real number of khash/s by a constant factor, which would urge people to use the modified client which in turn sends part of the coins to the author, without providing actually any benefits?

Has anyone verfied the odds of generating coins with the theoretical number [1]?
